Scutel1um very transverse, nearly twice .'IS wide as long; sides straight, oblique; apex truncate. Elytra only feebly attenuate apically; apices separately rounded; base each side with a broad gibbosity oblique toward suture, basal half rather densely, coarsely, and dooply punctate, sometimes feebly rugose, thence to apex punctures finer and less dense; humeri only moderately prominent, anterior margin arcuate, at angle a large rounded tubercle. Prosternum widened behind middle; mesosternal process angulate, emarginate medially; fifth sternite about one-third longer than fourth, subtruncate apically. Procoxae globose, internally with a broad but well elevated tubercle; profemora thick basally, gradually clavate to apex, transversely rugose on anterior and posterior faces on basal half. An tennae about twice body length; scape robust, not reaching middle of pronotum, gradually clavate, with one very deep and two or three more shallow grooves at base externally and internally, remainder of surface finely, densely punctate; third segment slender, moderately sinuate, about two times length of seape, one-third longer than fourth, remaining segments subequal; eleventh about one and one-half times tenth; fimbriate moderately on third and fourth segments. FEMALE. More robust and less attenuate apically; antennal tubercles only very feebly produced internally; fifth sternit eabout twice length of fourth, at apex feebly fringed, slightly emarginate and with a shallow triangular impression; pro coxae with a very obtuse tubercle internally; antennae about one-fourth longer than body; scape less robust.
